gloss
Merriam-Webster's Word of the Day for May 9, 2025 is: gloss • \GLAHSS\ • verb To gloss a word or phrase is to provide its meaning, or in other words, to explain or define it. // Many unfamiliar terms are glossed in the book’s introduction. See the entry > Examples: “It is revealing that early dictionaries regularly defined equality as ‘conformity,’ or glossed the word, like Noah Webster did in 1806, as ‘likeness, evenness, uniformity.’” — Darrin M. McMahon, The Chronicle of Higher Education, 1 Apr. 2024 Did you know? If you’re the type of word nerd who finds poring over book glossaries to be the bee’s knees, we know you’ll get a buzz from this gloss of the verb gloss. To gloss something, such as a word or phrase, is to explain or define it. The noun gloss, it follows, refers to (among other things) a brief explanation of a word or expression. And a glossary of course is a collection of textual glosses, or of specialized terms, with their meanings. Both forms of gloss, as well as the word glossary, trace back to the Greek noun glôssa, meaning “tongue,” “language,” or “obscure word requiring explanation.” Another descendent of glôssa, the English noun glossa, refers not to a bee’s knees but to a bee’s tongue, or to the tongue of another insect.

modicum
Merriam-Webster's Word of the Day for May 8, 2025 is: modicum • \MAH-dih-kum\ • noun Modicum is a formal word that means “a small amount.” It is almost always used with of. // The band enjoyed a modicum of success in the early 2010s before becoming an international sensation. See the entry > Examples: “Imagine, for example, that the gods decided to bestow upon Sisyphus a modicum of mercy. The rock, the hill, the never-ending, pointless labor all remained nonnegotiable as far as the gods were concerned, but the mercy of the gods was to change Sisyphus’s attitude to these things. … He is never happier than when rolling large boulders up steep hills, and the gods have offered him the eternal fulfillment of this strange desire.” — Mark Rowlands, The Word of Dog: What Our Canine Companions Can Teach Us About Living a Good Life, 2024 Did you know? It wouldn’t be wrong to say that the English language has more than a modicum of words referring to a small amount of something—it has oodles, from smidgen to soupçon. But while modicum can be applied to countable or physical things (like words or salt) it is almost always applied instead to abstract concepts like respect, success, control, hope, dignity, or privacy. Modicum traces back to the Latin noun modus, meaning “measure,” which just so happens to be the ancestor of more than a modicum of English words, from moderate and modify to mold and commode.

bumptious
Merriam-Webster's Word of the Day for May 7, 2025 is: bumptious • \BUMP-shus\ • adjective Bumptious describes people who are rudely and often noisily confident or over-assertive. It can also be applied to actions or behaviors that show this same attitude. // Our host apologized for the bumptious party guest who caused a scene before being asked to leave. See the entry > Examples: "She comes across as a bumptious, irritating ten-year-old who believes that her main vice, her steam-roller self-confidence, is a virtue." — Lloyd Evans, The Spectator (London), 17 Aug. 2024 Did you know? While evidence dates bumptious to the beginning of the 19th century, the word was uncommon enough decades later that Edward Bulwer-Lytton included the following in his 1850 My Novel: "'She holds her head higher, I think,' said the landlord, smiling. 'She was always—not exactly proud like, but what I calls Bumptious.' 'I never heard that word before,' said the parson, laying down his knife and fork. 'Bumptious indeed, though I believe it is not in the dictionary, has crept into familiar parlance, especially amongst young folks at school and college.'" The word is, of course, now in "the dictionary"; ours notes that it comes from the noun bump and the suffix -tious, echoing other disapproving modifiers including captious ("fault-finding") and fractious ("troublemaking").

exculpate
Merriam-Webster's Word of the Day for May 6, 2025 is: exculpate • \EK-skull-payt\ • verb To exculpate someone is to prove that they are not guilty of doing something wrong. // The editorial expresses confidence that the evidence will exculpate the accused. See the entry > Examples: “Research shows that social-media use is associated with greater narcissism (as well as depression and anxiety).... But it is too easy to exculpate ourselves as a society by pointing to technology and trends we can scarcely control, and young adults may not be in a position to address their avoidant behavior. The rest of us can help.” — Arthur C. Brooks, The Atlantic, 1 June 2023 Did you know? There’s no need to say “my bad” if you’re unfamiliar with exculpate; while the word is far from rare, it is most often encountered in formal writing in reference to the clearing of someone of alleged fault or guilt, as in “they were exculpated of any wrongdoing.” You may be more familiar with a pair of terms that, like exculpate, come from the Latin noun culpa, meaning “blame” or “guilt.” One is the adjective culpable, used to describe someone deserving of condemnation or blame. The other is the Latin phrase mea culpa, which translates directly as “through my fault” and refers to an acknowledgement of personal fault or error that is more formal than, well, “my bad.”

plethora
Merriam-Webster's Word of the Day for May 5, 2025 is: plethora • \PLETH-uh-ruh\ • noun Plethora refers to a very large amount or number of something. Plethora is most often used in the phrase "a plethora of." // The hotel offers a plethora of amenities, including indoor and outdoor pools, a fitness center, and world-class dining. See the entry > Examples: "In 1895, Japan won Taiwan from China in the Treaty of Shimonoseki, ending the Sino-Japanese War, and from 1895 to 1945, the island was a colony of Japan. The cultural influences of Japan persist to this day: in the tiny coffee shops with their enticing nutty aromas, in the plethora of Japanese-influenced sushi restaurants, and in Taiwan's highly efficient postal service and train systems." — Kim Liao, Where Every Ghost Has a Name: A Memoir of Taiwanese Independence, 2024 Did you know? Plethora was first used in English to refer to a medical condition marked by an excess volume of blood or other bodily fluid, with associated swelling and redness. (Its Greek ancestor, the noun plēthṓra, refers to a similar excess, or to general fullness or crowdedness.) These days, plethora is most often used in general contexts to refer to a large number or amount of something. While plethora conveys a plural meaning, it is a grammatically singular word, which makes choosing whether to pair it with a singular or plural verb confusing. Both can be correctly used, however; choose the singular if you wish to emphasize the grouping or collection ("a plethora of books is available"), and choose the plural if you wish to emphasize the individual elements or components ("a plethora of books have been written on the subject").
